Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617632, here are decompositions:

3 + 31617629 = 31617632
73 + 31617559 = 31617632
103 + 31617529 = 31617632
139 + 31617493 = 31617632
223 + 31617409 = 31617632
229 + 31617403 = 31617632
271 + 31617361 = 31617632
349 + 31617283 = 31617632

Showing the first eight; more decompositions exist.
